I booted from the live CD. The purple "Mythbuntu" screen showed itself properly for a few seconds. Then the (plymouth?) Mythbuntu-with-dots loading screen appeared, but it was rolling vertically. When that finished, the "choose your language" screen appeared, also rolling. I switched to a console via ctrl-alt-f1, and it also rolled.

Glen Ditchfield, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p xserver-xorg-video-nouveau REPLACE-WITH-BUG-NUMBER

Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful.
